Fish oils have a high content of highly unsaturated fatty acids which are prone to be easily oxidized during the preparation of the derivatives needed for most analytical procedures. As an alternative to these procedures, 1D and 2D NMR has emerged as a powerful technique for both fish oil analysis and the study of fish oil oxidation. This is a consequence of the large amount of information provided by this technique in a short time period and with a low risk of destruction of the highly unstable fish oil components. This review discusses recent advances in this subject, including determination of n3 and n1 fatty acid contents, relative positions of fatty acyl chains in triacylglycerol molecules, and the study of trans and oxidized fatty acids in fish oils.
